High Quality Refractory Magnesite chrome brick for glass furnace
Refractory Magnesite chrome brick
Magnesia Chrome Brick are direct-bonded and made from high grade magnesite clinker and chrome oxide. By high pressure shaping and
high temperature firing, its characteristic is the high direct-bonding rate, and big crystallite. It has a good thermal spalling
resistance. The low–basic neutral nature gives itself a good slag resistance when servicing low–acid feed furnaces.
The fused-rebonded brick are made of fused mgo chrome clinker,its a realistic lining material for refining furnace, electric
furnace, glass melting furnace,AOD COD RH etc.

Features
1. brick with characteristics of multi mineral composition, strong alkalinity, high density.
2. basic refractory magnesia brick is typical, the ability to resist the strong alkaline slag erosion.
3. of the refractory magnesia brick is also very high, generally can reach more than 2000 DEG C.
4. Magnesia brick load softening temperature is much lower than the refractoriness, is about 1500 degrees celsius.
5. Magnesia brick the thermal conductivity of magnesia brick is good ,low thermal insulation.
6. Magnesia brick thermal expansion, thermal shock stability.
1) Silicon oxide is above 95%.
2) Good acid erosion resistance.
3) High softening point
